evidence of change, it would be natural to suppose that during the nineteen centuries which have passed since Caesar's time, the action of the sea must have caused alterations in the coast, by wearing away the cliffs and headlands, and increasing the deposits on the low parts of the shore ; but in this respect we are not entirely dependent on conjecture, as various changes are distinctly recorded, though history does not reach, by some centuries, to the age of Caesar. The cliffs at Dover, and from thence to within a few miles of Folkestone, are of chalk, and therefore liable to be easily acted upon by the sea, and the state of the works next the edge of the cliff at Dover Castle shows that this hill formerly extended beyond its present limits. In the hollow occupied by the town of Dover, the land has undoubtedly advanced, and it was still advancing, by an accumulation of shingle, until the harbour of refuge, now in progress, was begun. At the end of the chalk next Folkestone is Eastwear Bay, where the cliffs become much lower, and the soil changes to a mixture of stone and clay; here the land periodically yields to the action of the sea. Immediately adjacent to this bay is the town of Folkestone, of which a considerable portion has been washed away. At Hythe the shore has advanced to some extent, and from hence the low tract of Romney Marsh, formed entirely by a deposit from the sea, reaches (under different names) to Rye, and to the hills below Pett, near Winchelsea; within this district important changes have arisen, but the history of them unfortunately is not perfectly clear; it seems certain, however, that in the time of the Romans, an estuary ran from Hythe towards Appledore, close under the high ground on which the church of Limpne (Lympe) stands, which possibly was an outlet of the river Bother, formerly called the Limene; here the Portus Lemanis was situated, and considerable remains of Roman buildings are still to be seen on the
